A developer has created a chat application with several advanced features over the past year. This application, currently available on a popular app marketplace, offers secure communication through RSA encrypted messaging, as well as voice and video call capabilities. One of the unique features of the app is the ability for users to generate and send customizable 3D avatars. These avatars can be interacted with by zooming in and out or rotating them for a more dynamic user experience. In addition to messaging and calling functions, users can also share stories and images within the app. The developer is now offering key components of the app for sale. This includes the source code for the client application, which is compatible with cross-platform software frameworks, as well as the backend source code. The sale also includes the source code for real-time messaging through SignalR Hubs. For the 3D avatar feature, the front-end source code developed using a popular JavaScript library is available. Additionally, the front-end source code for implementing video and voice calls using JavaScript and Web Real-Time Communication technology is part of the package. This offering is aimed at buyers interested in acquiring a well-rounded chat application with unique 3D features and secure communication capabilities.
